Step-by-Step: How to install AVG Anti-virus on your MacOS computer

Prerequisites:  You must have administrator access to the computer on which you want to install AVG


Currently, CSM does not have a standard for MacOS anti-virus software.  Each MacOS user is responsible for acquiring an appropriate product.  There are some no-cost options available for MacOS.  Each year MacWorld.com evaluates and rates both paid and no-cost anti-virus options.  In the most recent rating, AVG AntiVirus for Mac received their highest rating for a no-cost option.


 

1.  Acquire the AVG installation file.

Open up the Safari web browser and go to https://avg.com

Click on the FREE Download (for Mac) button.

Your Mac shows the download progress with the Downloads icon on your launcher bar.  If the download does not begin automatically, there is a link on the AVG web page to manually initiate the download.

When the download has completed you will see it when you click on the Downloads icon on your launcher bar.

 

2.  Install AVG.

Launch the installer by clicking on the avg_mac_security_online.dmg file.

The installation program launches.  Double-click your mouse on the installer icon.

MacOS security presents a warning about installing software from trusted sources.

Select Continue.

The installer proceeds.

Click Continue.

Read the End User License Agreement.

Click Continue.

Click the Agree button.

The installer notes how much disk space is needed.

Click Install.

The installer begins by downloading the installation files from AVG's server.

Enter your administrator credentials and click on the Install Software button.

The installation continues.

When the installation completes, you are presented with 1, possibly 2 pop-up messages.  The first, at the upper right-hand corner of the screen is AVG asking to be allowed to create desktop notifications.  Since this is an anti-virus program, it is prudent to allow it to let you know when something is detected.  Click the Allow button.

The second pop-up only appears depending upon which version of MacOS you have installed.  It is the operating system letting you know that there may be a problem in future with the AVG system extension.  We are going to allow the system extension to install and run.  AVG will address the possible future incompatibility with an update.  Click on the Open Security Preferences button.

The Security & Privacy dialog box opens.  Note the message about AVG Technologies software.

Click on the Click the lock to make changes icon.

Enter your administrator credentials.

Click the Unlock button.

When your administrator credentials are authenticated, the Allow button becomes enabled.

Click Allow.

After clicking the Allow button, the button and the notice about AVG will disappear.  Click the Lock Icon to secure the System & Privacy interface and close the dialog box.

The installation is now complete.

 

3.  Scan your system.

AVG anti-virus will now appear in the upper right area of the MacOS menu bar at the top of the display.

The first task is to ensure that AVG's threat definitions are up-to-date.  Click on the AVG icon and select Check for updates.

The main AVG interface opens and you will see Checking for Updates near the lower right-hand corner.

When the update process is completed, it will note: Up to date.

Near the bottom center of the AVG window, you'll see the Scan Mac and . . . (ellipsis) combined buttons.  

The ellipsis allows you to configure the scan options.  Click on the ellipsis to see the scanning options.

Mac Scan is a quick scan that checks the most vulnerable parts of the computer.

Deep Scan scans the entire system.

File Scan allows the user to select individual files or folders for scanning.

Schedule Scan allows the user to set up scans and paramters for repeated scanning.

For the first scan of your system, select Deep Scan.

The system scan commences and progress is displayed.  If you want to interrupt the scan for any reason, click on the Stop Scan button.

Once completed, AVG will display the scan results.  For the purposes of this document, I downloaded a benign test virus file from the  European Institute for Computer Anti-Virus Research at eicar.com.  AVG detected the threat.

The clean the threat, click on the Resolve All button.

AVG has quaranteened the suspect file.

Click the Close button to return to the main AVG interface.

 

4.  Enabling Full Disk Access permissions for AVG.

Depending upon which MacOS version you are running, AVG may notify you that Full Disk Access needs to be enabled.

If you click the See how link, you are directed to a web site that explains why AVG needs Full Disk Access to be most effective and you are presented with instructions on how to enable it.

For the purposes of this tutorial, I present the instructions.

Open up the MacOS System Preferences Utility and click on the Security & Privacy icon.

Unlock the dialog box by clicking on the Lock Icon in th elower left-hand corner of the dialog box and then enter your administrator credentials.

Click the Unlock button.

Scroll down the list in the left-hand column and highlight Full Disk Access.

Scroll down the list in the right-hand colum and add a check mark in the box next to AVG AntiVirus.

A pop-up notice will inform you that the change does not take effect until AVG is closed and restarted.

Click the Quit Now button.

Close the System Preferences dialog box and relaunch AVG.

Configuration is now complete.  

AVG's no-cost application provides basic system protection.  As such, you may be prompted occasionally to upgrade to one of their paid versions.
